So do the Yukon's have PWM? I recently picked up a 2019 Yukon SLT. I want to upgrade the Halogen headlights to LEDs. I have read LOTS of post about LEDs and which ones are the best etc... But I can't find anything about if the Yukon's have PWM. I thought the Tahoe's do because they use the headlights as DRLs, but the Yukon's have the LED DRL so the headlights should just use solid voltage. But in my readings about converting to LED's people say that some will show flickering and some will just turn off randomly.
